When we met, he told me he is looking for something serious. About 5 months, he was concerned we wanted different things as he wants marriage/kids in the next few years. With me, he will often say "look how cute that mother/father is with their kid" or "that'll be me as a husband babe" and often shows me houses/cost of houses in the areas that we go to. Thoughts? Or maybe he's just getting older?
